Acoustic Sciences Corporation, inventors of the Tube Trap, normally builds to order, but they have rebuilt the original high-speed TubeTrap production line and reset the jigs to produce a new, low cost TubeTrap that they will keep in stock. There's more good news. This 13 inch diameter x 36 inch high TubeTrap has 50% more absorption than the original and goes a full half octave lower, down into the problematic 70 Hz range. It still has a built-in treble-range diffusion panel to dial in that sparkling ambiance effect. It is finished, labeled and boxed like all TubeTraps. Priced at $398 each, they are part of a limited number of ASC products that are available only from ASC dealers. I am their dealer for Missouri and nearby Illinois. Their other products may be ordered direct, or through me for a better price. Their website is
